Red Hat Bugzilla – Bug 161255
Last modified: 2015-01-04 17:20:25 EST
Description of problem:
PXE network install of FC4 x86_64 *or* FC4 i386 on IBM BladeCenter HS20 (8843)
blade results in a kernel panic
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. setup a PXE install server
2. boot FC4 (x86_64 or i386) on an HS20 8843 blade
This is the IBM HS20 blade with the Intel Nocona (EM64T) processors.
KVM or MT (MediaTray) ownership is irrelevant, I tried it with both cases and
got the same panic.
Created attachment 115777 [details]
panic using x86_64 version of FC4
Created attachment 115778 [details]
panic using i386 version of FC4
after some more investigation:
passing acpi=noirq gives the same panic, but passing acpi=off allows the install
to succeed, but when the system reboots and loads the SMP kernel it ends up with
a kernel panic again.
But booting the UNI kernel after install works.
Both the SMP and UNI kernel have acpi=off
The same applies to both the i386 and x86_64 version of FC4
Check if this relates to the bug that I had here with a deficient initial root
disk image , Bug # 161406
there is no relation between this bug and the one mentioned by Joseph
[This comment has been added as a mass update for all FC4 kernel bugs.
If you have migrated this bug from an FC3 bug today, ignore this comment.]
Please retest your problem with todays 2.6.12-1.1398_FC4 update.
If your problem involved being unable to boot, or some hardware not being
detected correctly, please make sure your /etc/modprobe.conf is correct *BEFORE*
installing any kernel updates.
If in doubt, you can recreate this file using..
mv /etc/sysconfig/hwconf /etc/sysconfig/hwconf.bak
mv /etc/modprobe.conf /etc/modprobe.conf.bak
I installed 2.6.12-1.1398_FC4 x86_64 SMP kernel, and removed acpi=off from
grub.conf and rebooted.
I got one strange error on boot:
PCI: Cannot allocate resource region 1 of device 0000:00:00.0
Other then that the system booted fine, so the original issue appears to be
